Liza Minnelli will miss the 2010 Grammy Awards in Los Angeles later this month as she recovers from scheduled knee replacement surgery.

The legendary entertainer will undergo a surgical procedure to replace one of her knee at a New York-area hospital some time this week, but the operation will like Liza unable to attend the Grammys on Jan. 31, according to PEOPLE.com. Liza’s latest album, Liza’s at the Palace, recorded with the original cast from her Broadway show, is up for Best Traditional Pop Vocal Album.
“She is expected to make a full recovery,” her rep said in a statement Sunday.
